PURPOSE:To output the sound of singing voice or pronunciation, etc., emitted in accordance with the sound of song accompaniment or the pronunciation of a teacher reproduced from a video disk fitting in the sound of the song accompaniment or he pronunciation of the teacher, etc., to be reproduced later similarly by providing semiconductor memory, and a control means for the read/write and address of the semiconductor memory. CONSTITUTION:An audio signal inputted via a microphone 8 is stored in the semiconductor memory 22, and a write start address and the value of a code signal in accordance with the address, and a write completion address and the value of a code signal in accordance with the address are stored as a pair in table memory in the inside of a microcomputer 6. A stored audio signal is read out sequentially from the address of the semiconductor memory 22 in accordance with the value of the code signal, and a read out audio signal, after being converted to an analog signal by a D/A converter 23, is inputted to a mixing circuit 12 via switch circuits 2, 4 etc., and it is synthesized with the audio signal reproduced from the video disk, and is outputted. Therefore, when the practice of 'KARAOKE'(orchestration without lyrics) is performed, it is possible to evaluate and study the singing voice such as rhythm and an interval of a principle. |
